I just upgraded my florescents in the veg room with the 32 Watt 6 bulb fixtures from Home Depot. Each light is 17,500 Lumens so 35000 lumens for a 4 X 4 table. It's bright. I am running blue and red lights 6500K Daylight and 3500K soft White. By the time I bought chain and eye hooks and tax it was 100 bucks per lght.
I got mine from my local hardware store, not sure what u have where u live. I actually bought it as like a street light and use the fixture as a reflector
i got a 105w CFL 5000k for $21 at 1000bulbs.com. they have 105w 6500k available but thats like twice as much
